And then after HS, didnt Taegun went MIA? And then all we know is that he is with that mind manipulator esper who used (cos he is poor) & traumatized him when he is at his lowest, & he did some self harming before awakening as S rank esper. This is not really a spoiler since its already in the previous chapters.
I wanna know Taegun's back story more. Cos he is surely strong here but what happened aftr HS? I think there is more than what was previously said in the earlier chapters. Hope we got it soon since we have Eunsungs' now hehe.
